Method for determining the deviation of a control gear from an output preset angular position by use of permanent magnets mounted on the end of an output shaft so that they are opposite to a corresponding magnetic sensor

摘要

Method in which the deviation is determined using a magnetoresistive sensor integrated into the control gear. The front side of a free shaft end (22) of the output shaft (18) within the control gear is used as a support for the necessary magnets (1). Aligned opposite to the magnets is a fixed sensitive unit mounted on a support plate (2). The invention also relates to a corresponding control gear. When the output drive shaft is made on non-magnetic material, such as stainless steel, there is no need for magnetic shielding.
